Mother's hand is medicine.. It's more of a lullaby.
It's for when you're feeling sick. Rather than stuffing pills like the west, Korean mothers' rub their child's belly and sing this lullaby. Korean studies show at least 80% improvement. I couldn't find a video about this. Maybe @south_korea_ln can assist me in this topic?
it goes something like :
Mother's hand is medicine 2x
something, something dark side
Mother's hand is medicine 2x
